Revise: Chemical Plant DefencesA chemical defence response is different: the plant produces defensive chemicals after pathogen attack, helping it fight the infection.

If asked to describe a chemical defence response, identify the substance as antimicrobial and state its effect on microorganisms; merely naming a chemical is not enough.
